Closes #5291. Adds a randomized testnet generator. Nightly CI job will be submitted separately. A few of the testnets can be a bit flaky, even after disabling known-faulty behavior and making minor tweaks, and the larger networks may be too resource-intensive to run in CI - this will be optimized separately.

Closes #5428

Remove Response/Request SetOption from ABCI.

## Description

Closes: #5432

## Description

- Makefile: branches and path prefixes from `versions` work on `docs-staging` https://github.com/tendermint/tendermint/pull/5467
- Expects to have:
   - https://docs.tendermint.com/master
   - https://docs.tendermint.com/v0.32
   - https://docs.tendermint.com/v0.33

This was a missing test case from the old P2P tests removed in #5453, which makes sure that all nodes are able to peer with each other regardless of how they discover peers.

Fixes #2795, since the default CI testnet uses a combination of (partially meshed) persistent peers and PEX-based seed nodes.

## Description

fix broken link from a previous change

## Description

In blocks_results we use the proto definition of abciResponses: 2672b91ab0/rpc/core/blocks.go (L152-L155,) this leads to the use of the proto definition of the pubkey which is an interface in go (oneof). The interface must be registered with the JSON encoder to have it work correctly.

A clearer divide between proto types and native types is needed.

Closes: #XXX

Partial fix for #5291.

Partial fix for #5291.

This adds a basic set of test cases for core network invariants. Although small, it is sufficient to replace and extend the current set of P2P tests. Further test cases can be added later.

I forgot to add the date when we cut 0.33.5. This fixes that. It also fixes a header indentation issue for 0.33.8.

Partial fix for #5291. For details, see [README.md](https://github.com/tendermint/tendermint/blob/erik/e2e-tests/test/e2e/README.md) and [RFC-001](https://github.com/tendermint/tendermint/blob/master/docs/rfc/rfc-001-end-to-end-testing.md).

This only includes a single test case under `test/e2e/tests/`, as a proof of concept - additional test cases will be submitted separately. A randomized testnet generator will also be submitted separately, there a currently just a handful of static testnets under `test/e2e/networks/`. This will eventually replace the current P2P tests and run in CI.

Fixes #5371.

Required for #5291, to generate configuration files with state sync RPC servers.

Required for #5291 to set timeouts for remote signers.

previously, the second next could return nil, which would be the reason
for panic on line 275:

memTx := next.Value.(*mempoolTx)

Add information on p2p settings in documentation 

Closes: #XXX

## Description

Add simple `NoBlockResponse` handling to blockchain reactor v1. I tested before and after with erik's e2e testing and was not able to reproduce the inability to sync after the changes were applied

Closes: #5394

* docs: fix /validators description

Refs https://github.com/tendermint/spec/pull/169

* consensus: remove nil err from logging statement

* update UPGRADING.md

* note about LightBlocks

This change adds some polish to the upgrading instructions for 0.34. The only substantive changes include:
* Calling out ABCI-impacting changes explicitly in the "ABCI Changes" section, even if those changes are also mentioned elsewhere
* Removes `ProofOfTrialPeriod` from consensus params; this change was introduced and then removed.

Reduces the state sync discovery time from 20 to 15 seconds, and makes it configurable.

This caused the node to crash whenever any state sync-related request was called via the ABCI UNIX socket client.
